✓	🐛 Bug fix

Description

As identified by @kriek in #1828, part of the cache key (context) was missing.

Alternative to #1832, which removes the cache, this just adds the missing part of the key.

Closes #1828
Closes pylint-dev/pylint#7464
Closes pylint-dev/pylint#8074

Refs #1982 (reverted)

Pylint test

The following diff in pylint will (almost) pass the test suite with this change. ~~PR shortly.~~ PR once I can debug the remaining failures with deprecated_typing_alias.

Test improvements look nice!

jacobtylerwalls · 2023-04-30T14:25:22Z

Unfortunately it has the same problem in pypy with RecursionError identified in #2002, see https://github.com/jacobtylerwalls/pylint/actions/runs/4844716534/jobs/8633169007?pr=10.

Seems like the right approach, though, so we need to just deal with the RecursionError or something.

jacobtylerwalls · 2023-04-30T14:42:00Z

More history!

The test in question was skipped in #1984, then the skip was removed in #2000 when the decision was made to revert the substantive change dating to #1982.

Pierre-Sassoulas

Nice long-awaited improvements seeing the modification in the tests 😄

Sorry for the noise, I'm experimenting to see if I can get the recursion error in pypy to resolve.

for more information, see https://pre-commit.ci

jacobtylerwalls · 2023-04-30T17:36:42Z

RecursionError in PyPy fixed, see run on my fork failing on something else (compare to earlier run failing with RecursionError).

You've been contributing some serious improvements in perf/caching -that astroid and pylint needs most- @jacobtylerwalls, amazing 👌

Pierre-Sassoulas · 2023-05-06T13:34:30Z

The readthedoc fail could be fixed by pinning urllib3 to < 2 it seems ?

jacobtylerwalls · 2023-05-06T13:58:56Z

Others have solved it by ensuring Python 3.9 or higher is used for the build. Can we do that in a read the docs .yml?

jacobtylerwalls · 2023-05-06T14:00:59Z

Suggestions!

Fix read the docs in Use Python 3.11 for Read the Docs build #2165
I merge that here, someone approves this
Squash merge this
I open a new PR I just finished to improve the typing in this file: Improve typing of inference functions #2166
